Product details
The GBS12-120 belongs to the Zelus GBS series and is a valve-regulated sealed lead-acid battery using gel electrolyte technology. Its core lies in mixing sulfuric acid with fumed silica to form a fixed gel-like electrolyte, fundamentally solving the electrolyte evaporation, overflow, and resulting corrosion problems common in traditional flooded batteries. Gel batteries demonstrate superior performance, including greater resistance to extreme temperatures and excellent impact and vibration resistance. Their valve-regulated system can safely vent gases generated internally. The series batteries are structurally similar to wet batteries but use calcium instead of antimony in the lead plates; this change significantly reduces gassing tendency while maintaining mechanical strength.
The GBS series batteries offer overall voltage specifications of 6 volts or 12 volts, with a broad capacity range from 7 Ah to 225 Ah. Installation is flexible, supporting both horizontal and vertical mounting. Under normal operating conditions, GBS series batteries have an expected float service life of up to 12 years, or a deep cycle life of up to 2500 cycles, reflecting their design intent as deep-cycle batteries aimed at providing maximum capacity and lasting discharge cycle performance. According to the Eurobat standard, their service life falls into the long-life category. Specific capacity values, such as 120Ah here, refer to the Nominal Capacity at the C100 discharge rate; actual capacity varies with different discharge rates (such as C2, C5, C10, etc.).
The GBS12-120 model battery has a Rated Voltage of 12 volts and a Nominal Capacity of 120 Ah at the C100 discharge rate. Its physical dimensions are 407 mm in length, 173 mm in width, 210 mm in height, and 239 mm in total height, with a Weight of approximately 39 kg. The battery is equipped with standard I2 Terminal Type for easy connection. These compact and sturdy designs allow it to adapt to various installation environments.
The core advantages of this battery lie in its long cycle life and lasting performance maintained in high-temperature environments. The interior of the battery is completely filled with gel, which not only allows internal heat to be conducted more effectively to the casing, aiding heat dissipation, but also the gelled electrolyte effectively prevents acid stratification, improving battery stability and consistency. As a Maintenance Free battery, it requires no water replenishment throughout its service life. Its self-discharge rate is extremely low, with capacity loss of less than two percent per month, making it suitable for long-term standby storage.
Precisely controlled special valves are critical to battery cycle life, ensuring internal pressure is distributed and released within the optimal range. GBS series batteries are the ideal power choice for uninterruptible power supply systems, fire and security alarm systems, emergency lighting and monitoring systems, telecommunications facilities, medical equipment, street lighting and traffic signals, golf carts, floor cleaning equipment, and renewable energy systems such as solar and wind power. Whether ensuring network connectivity at communication base stations or storing unstable energy at wind farms, GBS batteries provide reliable and durable power support.
